Measurements
. Body length: 21.3–22.0; length of pronotum: 6.4–6.8; height of pronotum: 4.6–4.8; width of the pronotum: 1.5–2.0; length hind femur: 17.2–19.5; length of hind tibia: 18.3–21.5; length of tegmina: 31.1–37.3; width of tegmina: 7.6–8.1.
Remarks
. This species is only known from the
holotype
, a male collected at Lubumbashi (
Democratic Republic of
Congo
), and currently is the sole representative of the genus (
Massa 2015
). The two specimens listed above concur well with the description of this peculiar taxon, including its very narrow anterior part of the pronotum (see measurements), after which the Latin name of the genus.
Concerning the position of cerci, in the
holotype
are reported below the subgenital plate, but supposedly artificial in the mounted specimen. Actually the insect holds the cerci otherwise, above the subgenital plate. Cerci are very distinctive: their tip is black and chitinous, with the shape of a small spoon (
Figs 16A, 16B
). The stridulatory file, still not described, is
1.6 mm
long, nearly straight, and consists of ca. 45 evenly spaced teeth (
Fig. 16C
).
